Slate is commonly known to be grey in colour and can range from dark to light grey. Slate Slate is a low grade metamorphic rock generally formed by the metamorphosis of mudstone / shale, or sometimes basalt, under relatively low pressure and temperature conditions.Clay minerals in the parent rock metamorphose into mica minerals ( biotote, chlorite, muscovite) which are aligned along foliation planes perpendicular to the direction of pressure. Slate is preferred over artificial covering materials for its unique physical and chemical properties, moisture resistance, wind resistance, good insulating capability and cold/chill resistance. But as long as slaty cleavage is present, the slate will make a good roofing material. Slate is a naturally-occurring metamorphic rock.
